Yes, it is a specifically designed transformer and I'm sure Tom

I have a transformer company that might be able to
assist.? Does anyone know the exact spec of the Ameritron
AL-80B power transformer?? ?I'm assuming secondaries are?
9VAC @ 1.5A,? ?3.53VAC @ 15A, and 1100VAC @ .6A? ?I have
dug through the manuals and can't find anything specific.?
You can see the voltage doubler in the schematic though.?
And if 3100 No load volts is the DC target for B+??
?Thanks!? ?Warren? (WR0S)
